Chemistry

The Chemistry Kit is a valuable learning tool for Pri 3 up to Sec 2 students. It begins with the simple exploration of materials to more complex concepts like mass, volume, density, mixtures, solubility, crystallisation, as well as acidity and alkalinity. The user is guided through each of the explorations, with probing questions accompanied with interesting fun facts and real-life applications. These specially designed kits adopts the inquiry-based approach to learning Science, an approach that is central to the Singapore science curriculum framework. Research has shown that this approach helps to develop critical thinking and problem solving skills in children, skills which are vital for the workplace in the 21st century. Children learn best through self discovery and meaningful experiences, as they try to make sense of the world around them.The guided explorations are tailored to assist in the understanding of key science concepts in the Singapore science syllabus and are process-oriented to facilitate independent learning. They are written to engage children’s curiosity, to construct meaning in the learning of Science concepts, with the hope that they will develop positive attitudes and a passion for learning Science.

Explore and discover the process in water is filtered until it become clean. Water filtration is an important science and fascinating for the inquisitive mind.

The OHAUS CS is a lightweight, portable, compact balance perfectly suited for use in laboratory, industrial, education and home use applications. CS offers a great value without sacrificing accuracy for weighing jobs of 0-200g.

• Applications Weighing
• Display Liquid crystal display (LCD)
• Operation AC Adapter (Included) or 3 AA (LR6) Batteries (Included)
• Communication N/A
• Construction ABS Housing, Stainless Steel Pan
• Design Features Mechanical and software overload/underload protection, auto shut-off

The large weighing platform can accommodate larger samples and can also be removed for easy cleaning. Radio frequency protection allows the CS to deliver stable results even when used in areas in which radio waves may be emitted. The low profile CS is battery operated or can be powered by a standard AC adapter.

Students solve the case with ink chromatography and STEM.

• Hands-On STEM ActivityModel and Inquiry ActivitiesTeacher and Student
• Guides IncludedMaterial Accommodates up to 40 StudentsCovered Concepts
• Include Data Analysis, Chromatographs, and MoreThis kit introduces students to ink chromatography and its application in solving forensics cases.

They gain experience in creating ink databases, identifying ‘ink tags’ to ‘date’ various inks and then use them, as professional document examiners do, in solving two mysteries involving document inks—an apparent suicide note and a forgery case.Covered concepts include data analysis, chromatographs, inks and their composition-mixtures, compounds, mixtures, molecules, solubility, affinity, polar substances, Rf values, capillary action, light energy, fluorescence, and hypothesis testing.
